ANTISLIPPING DEVICE.

lTo aZZ whom'z't may concern: 7 Be it 4known that we, FRANK H. 'BACH- MAN andy REUBEN H. BACHMAN, citizens of the United States, residing at Allentown, in '5 the county of Lehigh andl State of Pennsylvania, have invented certain new and use-l ful Improvements in Antislipping Devices, of which the following is a specification, reference being had to the accompanying drawings. l I This invention` relates to certain improvej ments in anti-slipping'devices for Wheels, and it is an object of the invention to provide a device' of this general character having novel and improved means whereby they same may be readily and effectively applied toa wheel and whereby the device includes va plurality vof yieldably connected members.

'n .in'order to afford a meansfor relievin the motive power of a vehicle from the shoe s or jars incident to the use ofthe device.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our im- 2'5 proved anti-slipping device whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter 3o morefully set forth.

The novel features of the invention 'will' hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceedto describe the saine with reference to the accompanying drawings, wherein- Figure l is a view Iin elevation with parts in section of an anti-slipping device constructed in accordance withan embodiment 40 of our invention and in applied position; Fig. 2 isa view in side`elevation of one of the tread members herein employed; and Fig. 3 is a view in top plan of a tread member as herein disclosed'.

v lAs disclosedI-l the accompanying drawings, W denotes awheel of any ordinary or preferred type and with which our improved anti-slipping device is adapted to be employed. p p As herein embodied, our improvedvantislipping device comprises a plurality .of tread members 1 adapted to bridge the tread of the wheel W` and `having its extremities 'terminating in the inwardly disposed extensions 2 and provided with the eyesy 3.

provided with anysuitable means as indi- Coacting with each extension ,2 of a member l 1s a bar 5 provided'withl an'eye 6 whereby a pivotal connection is afforded with the eXtension`2. The pivoted end of the bar 5 is provided with an extension 7 arranged on a predetermined angle relative to the bar 5 and terminating in an inwardly disposed perforate ear 8 through whiclran adjacent bar 5 is adapted to be loosely directed. The second bar 5 is encircled by the spring 9 interposed between th/e ear 8 and' shocks or jars incident to travel are toa certain degree absorbed. This is of a particularadvantage yespecially as such absorption of shock isf/of'material benefit to the motive power o-f a vehicle with which our devices are employed.

From the foregoing description, it is thought to be obvious that an anti-slipping device constructed in accordance with our cated at l to afford an anti-skidding means.

invention is of an extremely simple and comparatively inexpensive nature andv is particularly well adapted for useby reason of the convenience and facility' with which it lmay be assembled, and it will also be obvious that our invention is susceptible of Asome change and modification without material departure from the principles and spirit thereof and for thisl reason We do not Wish to be understoodas limiting ourselves to the precise arrangementand formation of the several parts h'erein shown in carrying out our invention in practice.

We'claim: 1. An anti-slipping device comprising a pluralityv of tread membersbars pivotally 'engaged 'with the extremities of the tread .members each of said barsbeing provided with an extension terminating in a perforate ear, an adjacent-bar being loosely disposedthrough'sa'id ear, a stop carried by the portion of the bar disposed beyond the ear, and and expansible member interposed between said stop :and ear.

2. A n 'anti-slipping device comprising a plurality of tread members, bars pivotallyengaged with the extremities of the tread members, each of seid bars being provided with an inwardly disposed perforate ear, e bar of an adjacent tread member being loosely disposed through said enr, and en expansible member coasting with the ear and the outer portion of the bar disposed through the eer.

3. An anti-slipping device comprising e, 'plurality of treed members, bers pivotally engaged with the extremities of the tread members, each of seid bers being provided with an extension terminating in e perfo- FRANK H. BACHMAN. REUBEN H. BACHMAN.
